Abstract (en)
[origin: GB2424257A] A single cam phaser (SCP) camshaft comprises an inner shaft 12 and an outer tube 14, with a first group of cam lobes 16 fixed for rotation with the outer tube 14, and a second group of cams 18 mounted on the outer tube 14 but fixed for rotation with the inner shaft 12 and allowed limited rotation relative to the outer tube 14. The cams 18 that are fixed for rotation with the inner shaft 12 are connected to the shaft 12 by means of driving members 30 whose positions are adjustable in order to compensate for manufacturing inaccuracies of the shaft 12 or cams 18. The driving members may comprise a drive pin 32 firmly received in a bore in the inner shaft 12 and also in a sleeve 30 surrounding the outer tube. The sleeve 30 is further connected to cam lobes 18 mounted on the outer tube 14 by means of formations 36, 38 that permit the drive sleeve 30 to move transversely to the axis of the drive pin 32. Alternative embodiments include a compound drive pin 50, which may comprise a nut 50a and bolt 50b, may be barrelled (figure 7), and maybe locked into place by a fixing peg 34.
